Q. Evaluate the expression for p=3.9p = 3.9 and q=−3q = -3.\newlineWrite your answer as a decimal or whole number.\newlinepq−q=pq - q = _____
  1. Identify Expression: Identify the expression to be evaluated.\newlineThe given expression is pq−qpq - q. We need to substitute p=3.9p = 3.9 and q=−3q = -3 into this expression.
  2. Substitute Values: Substitute the given values into the expression.\newlineSubstitute p=3.9p = 3.9 and q=−3q = -3 into pq−qpq - q to get (3.9)(−3)−(−3)(3.9)(-3) - (-3).
  3. Perform Multiplication: Perform the multiplication.\newlineMultiply 3.93.9 by −3-3 to get −11.7-11.7.\newlineSo, the expression becomes −11.7−(−3)-11.7 - (-3).
  4. Simplify Expression: Simplify the expression by subtracting qq. Subtracting a negative is the same as adding the positive equivalent, so –11.7−(–3)–11.7 − (–3) becomes –11.7+3–11.7 + 3.
  5. Perform Addition: Perform the addition.\newlineAdd −11.7-11.7 and 33 to get −8.7-8.7.
